Design And Realization Of The Wireless TV Signal Monitor Instrument

It is a base task for the development of broadcasting and television to build a perfect monitor system. And it is also a main symbol of the current level of the broadcasting and television enterprise and an indispensable method and approach to improve the work efficiency, quality and level. Especially, it has important effects for improving the quality of wave transmission and playing, checking the effect of broadcasting and television net, sticking up for the air electric wave and the order of net station, protecting strictly and utilizing efficiently the frequency resource, commanding the examination in time, strengthening the management of broadcasting and television enterprise, and assuring that the customer can listen and watch perfectly. In our country, based on the premise that the quantity and cover scope is increasing continuously, the broadcasting and television enterprise develops in the direction of digital, intelligence, network and information. But, compared with the development speed of the cover net, the is too slower to satisfy the request of the business. Therefore that it is an urgent task to develop a broadcast and television monitor system with good performance and to constitute a system with new form. For satisfying this demand, the thesis proposed a design of wireless broadcast and tv monitor systemThe television monitor instrument realized receiving the multi-road television signal, auto searching for all channel,pausing and processing after searching for a channel,measuring and memorizing the field strength of carry wave and current status,returning to the search status manually, proceeding research until memorizing all channels the first time. after then,proceeding auto search,jumping memorized channels.,stop searching and alarming while finding new unknown channel, returning search status manually.
